>Safe, drama free, convenient to find, and clean. That pretty much says it all.
It starts with safe that includes the neighborhood and the parking lot not just the building.
I don't want to have to use my GPS just to locate a place (even though I probably will). That is convenient.
Clean is the easiest of all. Take a minute or two and put your clothes and other things in the closet. Tip the maid to get extra towels. (I have heard you can even get them to give you an extra set of sheets). Go to Walgreens or somewhere similar and get some of those trial/travel toothbrush/toothpaste kits or those small dixie cups and a bottle of mouthwash. Bring some unscented liquid soap so we don't have to share a bar of soap (or get some extra bars from your by now friendly housekeeper). If one of those travel things get used throw it away after the session. Bring a trash bag that you can remove the items from the bathroom wastecan and dispose of somewhere off site.
And as already stated candles, and music fix a lot of "undesirables" that a room may have.
